Index.html - "Preserve empty lines" does not describe the behavior

[bitwiseman]

Perhaps: "preserve allowed newlines"?

Hmm, yes, originally it actually preserved blank lines in the source, but somehow it has morphed into a generic "try hard to keep existing line breaks"

[bitwiseman]

I think it be came that because of problems like #56. Trying to guess whether and where people want lines to wrap.
